Well there is no way to directly start a submodule
(e.g. "git submodule create"), such that there has to be one repo
that actually has the git dir inside the working tree.
If the submodule exists already somewhere, there are 2 ways to do it
("git submodule add <URL>" or "git clone && git submodule add")
which lead to different outcomes, where the .git resides.

When starting a new submodule repo, yes, the git dir is inside
the working tree.

ok.

I talked to people in the office and got a heavy rejection on the
the work "embedded" here for another reason:
"Does it put the submodule on an embedded device?
What does embedded even mean?
The end user is super confused"
So I think we should not use embed or un-embed one way or the other.
Instead we need to have another name.
I think absorb is ok-ish, as "git submodule absorb" hints that the
superproject absorbs something from the submodule.
So I will reroll it with "absorb" fixing some nits pointed out by David?
